as did my '81, now with GM CS130 it usually doesn't although occasionally it too wants a little rpm, if you start the car without touching the pedal (possible with FI) and it idles for a few hours (who would do that?) without ever hitting the rpms necessary to "excite" the alternator, I suppose it's theoretically possible to run the battery down.........more likely a satellite will fall on your head due to decaying orbit, probabilities and all........
